Hold fast to Jesus and obey him. Let us hold fast the profession of our faith without wavering; (for he is faithful that promised;) And let us consider one another to provoke unto love and to good works: Not forsaking the assembling of ourselves together, as the manner of some is; but exhorting one another: and so much the more, as ye see the day approaching. 12 Wherefore seeing we also are compassed about with so great a cloud of witnesses, let us lay aside every weight, and the sin which doth so easily beset us, and let us run with patience the race that is set before us, 2 Looking unto Jesus the author and finisher of our faith; who for the joy that was set before him endured the cross, despising the shame, and is set down at the right hand of the throne of God. 3 For consider him that endured such contradiction of sinners against himself, lest ye be wearied and faint in your minds. 4 Ye have not yet resisted unto blood, striving against sin. 5 And ye have forgotten the exhortation which speaketh unto you as unto children, My son, despise not thou the chastening of the Lord, nor faint when thou art rebuked of him: 6 For whom the Lord loveth he chasteneth, and scourgeth every son whom he receiveth. 7 If ye endure chastening, God dealeth with you as with sons; for what son is he whom the father chasteneth not? 8 But if ye be without chastisement, whereof all are partakers, then are ye bastards, and not sons. 9 Furthermore we have had fathers of our flesh which corrected us, and we gave them reverence: shall we not much rather be in subjection unto the Father of spirits, and live? 10 For they verily for a few days chastened us after their own pleasure; but he for our profit, that we might be partakers of his holiness. 11 Now no chastening for the present seemeth to be joyous, but grievous: nevertheless afterward it yieldeth the peaceable fruit of righteousness unto them which are exercised thereby. 12 Wherefore lift up the hands which hang down, and the feeble knees; 13 And make straight paths for your feet, lest that which is lame be turned out of the way; but let it rather be healed. 14 Follow peace with all men, and holiness, without which no man shall see the Lord: 15 Looking diligently lest any man fail of the grace of God; lest any root of bitterness springing up trouble you, and thereby many be defiled; 16 Lest there be any fornicator, or profane person, as Esau, who for one morsel of meat sold his birthright. 17 For ye know how that afterward, when he would have inherited the blessing, he was rejected: for he found no place of repentance, though he sought it carefully with tears. 18 For ye are not come unto the mount that might be touched, and that burned with fire, nor unto blackness, and darkness, and tempest, 19 And the sound of a trumpet, and the voice of words; which voice they that heard intreated that the word should not be spoken to them any more: 20 (For they could not endure that which was commanded, And if so much as a beast touch the mountain, it shall be stoned, or thrust through with a dart: 21 And so terrible was the sight, that Moses said, I exceedingly fear and quake:) 22 But ye are come unto mount Sion, and unto the city of the living God, the heavenly Jerusalem, and to an innumerable company of angels, 23 To the general assembly and church of the firstborn, which are written in heaven, and to God the Judge of all, and to the spirits of just men made perfect, 24 And to Jesus the mediator of the new covenant, and to the blood of sprinkling, that speaketh better things than that of Abel. 25 See that ye refuse not him that speaketh. For if they escaped not who refused him that spake on earth, much more shall not we escape, if we turn away from him that speaketh from heaven: 26 Whose voice then shook the earth: but now he hath promised, saying, Yet once more I shake not the earth only, but also heaven. 27 And this word, Yet once more, signifieth the removing of those things that are shaken, as of things that are made, that those things which cannot be shaken may remain. 28 Wherefore we receiving a kingdom which cannot be moved, let us have grace, whereby we may serve God acceptably with reverence and godly fear: 29 For our God is a consuming fire.
But all it takes is ONE sin to keep us from being able to be in His presence.
Adam and Eve sinned only one sin and for that death came into the world, they were kicked out of the Garden, and God promised the needed Redeemer.
You could live a perfect life except for ONE sin, and still not make it into heaven because God’s standard is ABSOLUTE perfection, perfection as the Father is perfect.
Obeying God is good, and has value, but it is totally useless and worthless to attaining eternal life because it CANNOT erase the record of debt we owe, that is death, for that first sin that was committed.
There is the additional complication that we are sinners. We are not sinners because we sin. We sin because we’re sinners and our very nature and all that we do is tainted and corrupted by and with sin. So even that entire life of obedience is still not going to be effective because none of our works are pure enough to count for salvation. They are as filthy rags in God’s sight.
THAT is the reason we need forgiveness granted from the Father and the righteousness of Jesus credited to our account.
The ONLY way to have the kind of perfection that God demands of us. That is that HE Himself gives it to us.
The law wasn’t put into place so that by keeping it, we could become or be made righteous. It was put into place to show us that we COULDN’T do it on our own and lead us to Christ so that we could throw ourselves on the mercy of the court and be given the forgiveness we don’t deserve and can’t earn.
It’s then we are born again and given the new nature that God requires of us, one that, when this body of flesh is dead and gone, gives us the ability to stand before Him in His presence, acceptable in His sight.
